JOHN I. MGGILL, OF BUFFALO, NEW YORK, ASSIG'NOR 0F ONE-HALF T0 MARSHALL LAPHAM, OF BUFFALO, NEW YORK.

PILE.

To all whom it may concern Be it known that I, JOHN I. MCGILL, a citizen of the United States of America, and a .resident of the city of Bufialo, in the county of Erie and State of New York, have invented certain new and useful Tmprovements in Piles, of which the following is a full, clear, and exact description.

My invention relates generally to improvements in piles and more particularly to those piles that are adapted for use in construction where water, quicksand or soft earth are met with and have to be excluded from the construction work.

Some of the objects of my invention have been to produce a metal piling made up of duplicate sections which are capable of interlocking with each other without fabrication, and which, when so interlocked, are also capable of withstanding any longitudinal strain put upon them; again, my invention may be employed not only to form a longitudinal wall of any desired length but it may also be interlocked into a four-sided wall surrounding an inclosure of any desired size and longitudinal continuations of any side of such inclosing wall may be securely locked therewith as desired.

Other advantages resulting from the use of my invention will be clear to those who are skilled in the art after they have examined the accompanying drawings and the following description.

In the drawings: Figure 1 is a plan view of two sections of my pile interlocked. Fig. 2 is a plan View of several of my sections interlocked into an inclosing wall structure and also showing other sections interlocked therewith in such a manner as to provide longitudinal extensions of any one or more of the side sections of such inclosing wall.

The pile sections A are duplicates of each other. Each section comprises a Web 1, one edge or end of which is provided with two lateral-hook flanges or backwardly turned bearing terminals 2 and 3 so that the extremities are deflected over the web 1. The other edge or end of said web 1 is split and provided with outwardly and inwardly proj ecting hooks spaced apart so as to form two curved lateral wing sections 4: and 5 between which is provided a slot 6 Which is in parallel plane with, and slightly wider than,

said web 1. Between the lateral winged sections 4 and 5 is formed an elliptical recess 7 Specification of Letters Patent.

which at its greatest diameter is somewhat longer than the greatest width of the lateralhook-flanges 2 and 3. The head or outside periphery of the hooked flanges is curved as clearly shown and the circumference of the recess 7 is also curved so that when the hook flanged end of one section is interlocked with the recessed end of another section the periphery of one is capable of rotating about 30 within the circumference of the other as clearly shown in dotted lines in Fig. 1. By virtue of this construct-ion, the wall of piling formed by a series of interlocked sections, may be made straight or it may be curved as desired, each pair of adjacent interlocked sections being capable of rotation within certain limits as described. This is a. great advantage, since it provides for a departure from a straight longitudinal wall and it is well known that, in driving piles, obstructions, as for example, boulders, are sometimes met with, and the wall of piling cannot be built on a straight longitudinal line.

When a series of sections are assembled into an interlocked longitudinal wall the lateralhook-flanges 2 and 3 of one section pass within the recess 7 of the next adjoining section and the web of the first section is received within the slot 6 of the second sect-ion. The joint thus made is a loose joint and is capable of rotation as described.

If it is desired to form a four-sided wall with my pile sections, the recessed edge of one section may be locked with either one of the lateral-hook-flanges 2 or 3 of another section as clearly shown in Fig. 2. In this manner a four-sided pile structure of great strength and of any desired size may be readily built. Should it be desired to extend one or more of the walls of such foursided structure then the recessed edge of a section forming such extension may be placed facing the recessed edge of the last section in the wall to be extended and the unengaged hook flange of the section at right angles thereto may then be locked within the recess of said extending section all of which is clearly shown in Fig. 2. Of course further extensions may be made in the manner shown in Fig. 1.

It is clear that the flanges 2 and 3 must be of a hooked or curved formation as clearly described and shown since the hooks 2 and 3 must interlock with the curved flanges l and 5 of the recessed edges of the sections. If the flanges 2 and 3 were straight, when interlocked into a rectangular wall similar to that shown in Fig. 2, they would slip from engagement with the recessed ends of the other section and provide thus a very insecure joint.

Obviously my invention is not confined to the exact conformations herein shown and described but some changes may be made therefrom without departing from its spirit and without sacrificing the advantages secured by it.

What I claim is:

1. A pile section, comprising a web, a lateral-hook-flange at one edge and two lateralcurved-wings forming a recess at its opposite edge, said recessed edge being capable of receiving in a interlocked union the lateralhook-flange of another section.

2. A pile section comprising a web, two lateral-hook-flanges at one edge and two lateral-curved-wings forming arecess at its opposite edge, said recessed edge being capable of receiving in an interlocked union one or both of the hook flanges of another section.

3. A pile section comprising a web, two late-ral-l1ook-flanges at one edge and two lateral-curved-wings forming a recess at its opposite edge, said recessed edge being capable of receiving in an interlocked union one or both of the said hook flanges of another section and said lateral-curved-wings being spaced apart so as to form a slot slightly wider than, and in parallel plane with, said web.

4. A pair of piles having sliding, interlocking connection with each other and each of them comprising a lateral-hook-fiange at one edge and two lateral-curved-wings forming a recess at its opposite edge, said recessed edge being capable of receiving in an interlocked union the said lateral-hook-fiange of the other section.

5. A pair of piles having sliding, interlocking connection with each other and each of them comprising a Web, two lateral-hookflanges at one edge and two lateral-curvedwings forming a recess at its opposite edge,

said recessed edge being capable of receiving in an interlocked union one or both of the said hook flanges of another section.

6. A pair of piles having sliding, int-erlocking connection with each other and each of them comprising a web, two lateral-hookiianges at one edge and two lateral-curvedwings forming a recess at its opposite edge, said recessed edge being capable of receiving in an interlocked union one or both of the said. hook flanges of another section and said lateral-curved-wings being spaced apart so as to form a slot slightly wider than, and in parallel plane with, said web.

7. A metal piling composed of pile sections having sliding, interlocking connection with each other, each of said sections comprising a web, two lateral-hook-fianges at one edge and two lateral-curved-wings forming a recess at its opposite edge, said recessed edge being capable of receiving in an interlocked union one or both of the said hook flanges of another section.

8. A metal piling composed of pile sections having sliding, interlocking connection with each other, each of said sections comprising a web, two lateral-hook-fianges at one edge and two lateral-curved-wings forming a recess at its opposite edge, said recessed edge being capable of receiving in an interlocked union one or both of the said hook flanges of another section and said lateralcurved-wings being spaced apart so as to form a slot slightly wider than, and in parallel plane with, said web.

9. A rolled metal pile having at one edge two lateral curved wings forming a recess, and at the other edge a head having a lateral-hook-fiange, said recessed edge being capable of receiving in an interlocked union the head of one or more of the hook flanges of another section.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.
